The 50mm extended-range thermal PTZ flagship

The Hikvision HM-TD4137-50/WY is the flagship of the thermal PTZ range. 50mm thermal lens for extended-distance thermal detection (suited to multi-hundred-metre perimeter applications), 4MP optical channel with 40x optical zoom for sharp identification at distance once the camera locks on, full pan-tilt-zoom motor control, and Hikvision smart tracking that follows detected thermal events automatically.

The right call for very-long-perimeter applications where both thermal detection AND active PTZ coverage are the requirements: large industrial sites, mining operations with extensive boundary runs, critical infrastructure, and any application where the standard 25mm thermal PTZ is insufficient on detection distance.

What this camera is actually good at

  • 50mm thermal lens for extended-distance thermal detection.
  • 4MP optical channel with 40x optical zoom.
  • Full pan-tilt-zoom motor control.
  • Smart tracking following detected thermal events automatically.
  • Bi-spectrum design with simultaneous thermal and optical channels.
  • Heavy-duty IP66 weather-sealed housing.

Where this camera belongs

  • Very-long-perimeter industrial site monitoring
  • Mining operations with extensive boundary runs
  • Critical infrastructure with extended thermal-detection requirements
  • Large agricultural and forestry operations
